  • 研究方向

    涡被称作流动的“肌腱”,其本质是流体中力的作用和动量的输运,是很多非定常和不稳定流动现象的根源,是湍流的重要元素。发动机燃烧室的不稳定性机理较为复杂,涉及喷雾、化学反应、热流乃至声波之间的相互作用。利用涡动力学的分析方法结合实验和数值模拟的手段有助于从本质上理解喷雾燃烧中的不稳定性现象,排除次要因素,精确锁定导致不稳定性的主导机制;进而发展主动流动控制技术抑制不稳定性产生的源头,从而实现对稳定燃烧的强化。主要研究方向如下:

    应用
    1. 喷雾燃烧
    2. 燃烧不稳定性
    3. 合成射流与流动控制

    理论
    1. 涡动力学
    2. 非定常空气动力学
